A fuel tank support system for providing a lightweight yet strong structure for supporting propane tanks above a ground surface. The tank support generally includes an elongated support pad having a platform, a base plate connected to the support pad, and a plurality of internal supports connected between the support pad and the base plate. A plurality of pairs of upper retainer rings extends from an underside of the platform to define upper receiver slots, and a plurality of pairs of lower retainer rings extends from an upper side of the base plate to define lower receiver slots. An upper end of each of the internal supports is received by the upper receiver slots and a lower end of each of the internal supports is received by the lower receiver slots. Handles, bottom grooves, and internal ribbing are also used with the tank support.
